I To aZZ whom it may concern:

Be it known that we, Knur- Asntrnn and TEOFRON 'BOBERG, subjects of the King of Clarence Road, -Gla'pham Park, London, England, Great Britain, have invented new anduseful Improvements in Aromatizing Dry Coffee Extract, of which the following is a specification.

Our invention relates to improvements in aromatizing dry cofi'ee extract such as is obt'ained by treating ground roasted codes beans with hot water and evaporating the solution, and the object of our,improvements is to produce a dryv coffee extract which when dissolved in hot water will g ve {a beverage possessing flavor and .aroma very 'losely approaching that made from freshly ground coffee beans.

We have observed that ordinary cofi'ee contains a much larger proportion of-the aroma;possessing substances than is necessary, and that if the, amount thereof is reduced until only some two or three per cent.

remains no perceptible difference is produced as regardsthe fragrance of. the resulting beverage. According. to our." invention, therefore, the aroma is imparted to the dry cofie'e extract by adding to the latter a small quantity of finely ground roasted cofiee beans.

with the dried from the greaterportion of tlieoofiee beans l Incarrying' our invention. 'ntoefiect, the greater portion of a quantity f roasted coffee beans is ground and extracted with hot water. The solution is then. filtered and evaporated and the resulting residue re duced to a by Weight of the original coffee beans ground to powder of such fineness as to be capable of suspension in the subsequently prepared beverage, is then intimately/mixed and ground extract \xmade fine powder. One to five per cent.

above referred to. mixture composition this invention) may be made into pellets by any suitable means. The quantity of insoluble matter introduced with the finely If desired the'resultin'g ground beans is so small as to produce no objectionable quantity of sediment in the beverage.

In finely grinding the roasted cofi'ee beans, as above) referred to, the natural fatpresent may be found toucause formation of sticky lumps whieh may interfere with the grinding. In such case the efiectof the fat may be neutralized by adding some of the dry coffeeextract inorder to reduce the average fat ground.

Weclaim:

1. In the grinding of roasted cofiee beans into a fine powder, the addition to sue beans of a; suitable quantity of dry cofiee extract to prevent the formation of a sticky mass while grinding.

2. A 'dry coffee composition for produ c' ing' a beverage composed of ground dry excontentof the mass being tract derived from coffee beans intimately. mixed with a fine powder derived from grinding roasted codes beans.

3. A dry coffee composition for producing a beverage composed of ground dry extract of. roasted 'cofiee. beans intimately mixed with a fine powder derived from grinding .roastd cofiee beans, the relative amount of the'said powdered cofi'ee beans being from '-one to five per cent. by weight of theoriginal cofl'ee beans used in preparing the extract and thefine powder: J
